Heat
gained or absorbed in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. We need data on the heat capacity of iron. From literature, it is 0.450 J/g-C. We use the expression as follows:
Heat absorbed= m (C) (T2-T1)
Heat = 48 g (0.450 J / g-C ) (111 C - 8 C)
Heat = 2224.8 J energy
gained
Therefore, the heat that is absorbed by the given mass of iron skillet from the rise in temperature of 8 degrees celsius to 111 degrees celsius would be about 2224.8 Joules of energy.
